I was attempting to access the records via the Portale della Storia degli italiani website.

Both times that I tried to register, no link to activate my account was sent to me. I sent an e-mail requesting assistance to the tech services address for the site, but the e-mail was returned as undeliverable.

here is a link, it seems that it depends on your email account you might not get a confirmation email. But I know for sure the with gmail there are no problems. sign up and is free and you can change the language to English and now you can even order copies for free!!!
